When the architectural community wants to select the most durable coatings in the industry, what resources are available? The American Architectural Manufacturers Association (AAMA) has created stringent performance standards. For years, AAMA 603 and AAMA 605 were recognized as the standards for testing and performance of organic coatings for architectural aluminum panels and extrusions.
Recent advances have created a need to update these voluntary specifications. Now AAMA 2605 is the most stringent high-performance exterior specification for “superior performing organic coatings on aluminum extrusions and panels,” with increased performance compared to that required by AAMA 605.
Extensive testing is used to determine if coatings on panels meet performance requirements. Testing includes dry film hardness, adhesion, impact resistance, chemical resistance and abrasion resistance.
To determine exterior durability, coated panels undergo ten years of testing in Florida, where coatings are exposed to harsh UV light, salt spray, sand and humidity before color retention, chalk resistance, gloss retention, erosion resistance and dry film thickness is tested.
The 70-percent polyvinylidene fluoride resin-based coatings meet this demanding architectural specification—that includes Valspar's Fluropon and Flurospar coatings for monumental applications, as well as our new Acrylic resin coating Acropon for non-monumental applications. These time-proven coatings are used for curtain walls, louvers, sunshades, entry systems and monumental window wall systems. They are available in nearly any color, including solar reflective coatings and Kameleon colors.
Selecting coating systems is a major decision. Using products that meet stringent AAMA guidelines ensures coatings meet certain standards for aesthetic and protective qualities.
